Stellar angular momentum (λ_Re) plotted against the ellipticity (ε_e, left) and concentration (R₉₀/R₅₀, right) for the GalMer simulations (original models and merger remnants), in comparison to CALIFA galaxies. All the parameters correspond to an edge-on view. The dotted line in the left plot represents the division between fast and slow rotators, and the top axis in the right plot is from Gadotti (2009), valid only up to (B + bar) /T < 0.6. See legend at the right for the symbols and colour-coding.
